RESUMEN

PURPOSE: Examine the beneficial effect of early nasogastric tube (NGT) removal in patients undergoing radical cystectomy with urinary diversion. PATIENTS AND METHODS: 43 consecutive patients underwent radical cystectomy with urinary diversion and were randomized into 2 groups. In the intervention group (n = 22), the NGT was removed 12 hours after the operation. Comparatively, in the control group (n = 21), the NGT remained in place until the appearance of the first flatus. The appearance of ileus, patient ambulation, time to regular diet, and hospital discharge of the two patient groups were assessed. Patient discomfort due to the NGT was also recorded. RESULTS: The 2 groups showed statistical homogeneity of their baseline characteristics. Two patients (9.09%) from the intervention and 3 patients (14.3%) from the control group developed postoperative ileus and were treated conservatively. No significant differences in intraoperative, postoperative, bowel outcomes or other complications were found between the two groups. All patients preferred the NGT to be removed first in comparison to their other co-existing drains. CONCLUSIONS: This is the first randomized, prospective study, to our knowledge, to assess early NGT removal after radical cystectomy. We advocate early removal, independently of the selected type of urinary diversion, since it is not correlated with ileus and is advantageous in terms of patient comfort and earlier ambulation.

RESUMEN

AIMS: To determine whether alpha1-blocker treatment, in chronic bladder outlet obstruction (BOO), influences bladder tissue ischemia. MATERIALS AND METHODS: This prospective study included 60 patients with BOO, of which 40 were under alpha1-blocker medication and 20 without treatment. Patients underwent transurethral resection of the prostate (TURP) or suprapubic prostatectomy (SPP). Ten patients with non-muscle invasive bladder cancer underwent transurethral resection of the bladder tumor and served as the control group. Tissue specimens were immunohistochemically stained for hypoxia inducible factor-1alpha (HIF-1alpha). RESULTS: Bladder tissue from obstructed subjects showed high immunoreactivity to HIF-1alpha. The specimens from the control group, showed no or weak, mainly cytoplasmic immunoreactivity to HIF-1alpha. Patients under alpha -blocker treatment did not differ in the number of HIF-1alpha positive cells compared to subjects with no treatment (median number 86.8 [20-150] and 88.6 [0-175], respectively) (p > 0.05). The lowest bladder pressure at which HIF-1alpha was up regulated, was detected at detrusor pressure Qmax (PdetQmax) = 60 cm H2O. CONCLUSIONS: Treatment with alpha-blockers in obstructed patients considered as non-responders, does not result in HIF-1alpha down regulation, thus bladder continues to be under chronic stress.

RESUMEN

AIMS: To determine whether á1-blocker treatment, in chronic bladder outlet obstruction (BOO), influences bladder tissue ischemia. Materials and methods: This prospective study included 60 patients with BOO, of which 40 were under á1-blocker medication and 20 without treatment. Patients underwent transurethral resection of the prostate (TURP) or suprapubic prostatectomy (SPP). Ten patients with non-muscle invasive bladder cancer underwent transurethral resection of the bladder tumor and served as the control group. Tissue specimens were immunohistochemically stained for hypoxia inducible factor-1á (HIF-1á). Results: Bladder tissue from obstructed subjects showed high immunoreactivity to HIF-1á. The specimens from the control group, showed no or weak, mainly cytoplasmic immunoreactivity to HIF-1á. Patients under á -blocker treatment did not differ in the number of HIF-1á positive cells compared to subjects with no treatment (median number 86.8 [20-150] and 88.6 [0-175], respectively) (p > 0.05). The lowest bladder pressure at which HIF-1á was up regulated, was detected at detrusor pressure Qmax (PdetQmax) = 60 cm H2O. Conclusions: Treatment with á-blockers in obstructed patients considered as non-responders, does not result in HIF-1á down regulation, thus bladder continues to be under chronic stress.
